Application filled July 7, 1910,. lSerial No. 570,892.` A *l n To all Iwhom it may concern:

`Be it known that I, ERNST WEBER-STIER- LIN, engineer, la citizen of the Swiss Confederation, and resident of Forchstrasse 136,-

Zurich, Switzerland, have invented new and useful Improvements in Gas-Distributing Devices, of which the following is a speciication.

My invention relates to apparatus for distributing gas in liquids, devices of which kind are used for regenerating the water in fishV receptacles, or for the preparation of baths for the treatment of rtain maladies.

An object of my invention is to provide a device with which a great number of very small bubbles can be formed which are of a uniform size.

A further object of my invention is to provide a device which will not deteriorate even after a long use and whichwill retain its facility for forming bubbles of a small and uniform size.

I attain'these objects by compressin a quantity of hair-like material, preferagbly inlayers, in a retainer adapted to contain the material and by forcing the air or gas through the material in such a manner that the air or gas is finely divided and rises'n small bubbles, from apertures in the container, through liquid containedv in the receptacle lin which my device is placed.

In the accompanying drawings, forming apart of this specication,-Figure'1 is a central longitudinal section through a container embodying my invention. Fig. 2 is a sectional View taken on the line A-B of Fig. 1. Fig. 3 is a central vertical section through a modified form of my device. Fig.

4 is a perspective View showing the application of the device disclosed in Fig. 1, arranged in series, and placed in a bathtub,

`part of the latter being shown in section.

With special reference to Figs. 1 and 2, I provide an inner and outer tube 1 and 7,

respectively, arranged concentrically. .The

lturning one of the plugs 8. One end ofthe tube 1 is closed by means of a plug ,5, the other end of which is adapted to be connected to' al main, supplying compressed g-as, such as air, or carbon dioxid gas. The inner tube is provided, .preferably at its under side,.with a number of apertures 2 for egress of the gas from the tube. The

outer tube 7 is provided, preferably at itsv upper side withv a plurality of `slots 6, for

egress of the gas from the device.- By this preferred arrangement of apertures it will be -seen that the gas must pass Ythrough a greater section of the hair-like material than if otherwise arranged and upon leaving the device rises vertically, which construction prevents the bubbles forming on the outer walls of the tube 7 and uniting there.

As shown in Fig. 4 the tubes may be ar- 'ranged in series with a common main servis made to the gas supply pip-e 20, and an annular flange 11b. Arranged superjac'ent to the plate 11, and resting on the ange 11a thereof, is a plate 12 having a plurality of openings 13.

Retaininv means for the hair-like material 14;, preferably arranged in layers superjacent to each other, disposed upon the.

plate 12, is made up of side pieces 18 consisting of angle iron lhaving unequal legs, the longer legs of which are in lateral abutting relation vto each other, and disposed upon the short leg of theupper angle iron is a plate 15v having a plurality of openings 18, which forms the top of the retainer.

In order to hold the retaining means in' place, and to provide means for compressing the material-contained therein,a ring 16'is' placed above the plate 15 and connected to the plate 11 by 'means of bolts 17 and nuts 17%. By this construction itfwill be seen` that material containedwithin the retainer may be compressed or released by turning the nuts 17 a, the side of the retainer being collapsible. y

, The hair-like material,.which in fact may be animal hair, usedasa filling for the tube does not decay andp'reserves its elasticityfor years. It is essentialthat the degree of compression ofthe" filling material be as uniform as possible throughout its sectional area. In -this` connection, I have found kit desirable toarrange-the hair-like material in layers, compressing each layer in place.

It isto' be understood'thatI do not limit myself to the forms of retaining means ,shown in the drawings-since any combinations of parts which` will hold the-hair-like material under uniform compressionhand the introduction of the gas atsuch aipolnt lthat it will be forced through thematerial before.

leaving a lretainer maybe used without de.- tracting from the spirit' of my invention.

Icla1m:- 1. A device for distributing gasthrough a liquid comprising in combination, an outer into the outer tube and provided withl openl l rality of compartments with bodies of hairtube having openings therein for egress o fthegas, an inner delivery tube extending ings and adapted to beconnected with the source of supply, :rf-plurality of diaphragms dividing space between -slaid tubes into a plurality of compartments with bodies ofhair between said diaphragms .and filling the space between said tubes, and means'fo'r compressing and-retaining said hair bodies and diaphragmsin close relation.

2. A device for distributing gas through a liquid comprising in combination, an.outer tube havin openings therein vfor egress lof the gas, an mnerdelivery tube extendmg into the outer tube and provided with openings for discharge of the gas, a plurality of imper- `fo'rate diaphragms dividmg the space lbetween said tubesinto aplurality of compartments withl bodies of hair between said diaphragms .and -lling the' space between said tubes, and means for closingone end of said outertube and compressing the hair bodies and diaphragms therein.'l

3. A device for distributing' gas through liquid comprising in combination, an outer hollow member having openings for egress of. the gas, a member adapted for connection wlth a. source of supply of the'gas and exltending into and. delivering to said outer member, a plurality of diaphragms dividing the space between said membersinto a plucompressin members and ,diaphragme and m for compressing the material Aand diaphragme,

ubsll'iantiallyj as yand for 4the purposes set 4. A device for distributing gas through `like material the spaces betwe n said liquid comprising in combination, an outer hollow member having openings lfor. egress of the gas, a member adapted for connection with a 'source of -supply of gas and connected to deliverto said outer member, a-plurality of diaphragme dividing said outer member'l into a plurality of compartments witl1bod l .ies of hair-like material filling the. spaces be'- nected with a gas supply,l and compressedfibers between said tubes.

6. A device for dlstrlbutmg gases. 1n liquids com rising in combination", an outer tube with s o'tstherein, means closing the' ends of said tube, a second tube with slots placed cocentrically within saidv tube adapted to. be connected toy a gas supply pipe, and aI compressible filling of halr 1n the .space between said tubes.A I

7. A device for distributing gases in liquids 'comprising -in y. combination, a retainer having y-a plurahty of aperturesl formed therein, a member adapted for connection with a source of supplyof gas yand connectedto deliver to said retainer, a filling comprising a plurality of layers of compressed hair-llke material disposed within.

said retainer, and means for uniformly compressing said material with said retamer.
